Benefits of technology

The invention is a liquid crystal display that can prevent staining caused by variations in the gap between the substrates. This is achieved by using step compensating members that are formed at the space between data driver ICs and which can adjust for changes in the gap. The method of manufacturing this display also includes certain processes to ensure that the gap between the substrates is uniform and the display is of high quality. Overall, this invention provides a solution to a common issue that can affect the quality of liquid crystal displays.

Problems solved by technology

This problem is more serious in high-resolution liquid crystal displays, such that stains can be generated near the data voltage supply lines when the liquid crystal display operates.
This also leads to the above-described problem of non-uniform cell gap.

Embodiment Construction

[0058]The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

[0059]In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Like reference numerals designate like elements throughout the specification. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present.

[0060]A liquid crystal display according to a first exemplary embodiment of the present invention is described ...

Abstract

A liquid crystal display that includes: a first substrate and a second substrate each including a display area and a non-display area, the display and non-display areas positioned opposite to each other; a plurality of data driver ICs formed in the non-display area of the first substrate; a plurality of data voltage supply lines connected to the data driver ICs and extending to the display area of the first substrate; a sealant positioned between the first substrate and the second substrate to surround the display areas; and a step compensating member formed outside the sealant on the non-display area of one of the first substrate and the second substrate, in which at least some of the data voltage supply lines extend under the sealant, and the step compensating member is positioned generally inline with the at least some of the data voltage supply lines.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to, and the benefit of, Korean Patent Application No. 10-2010-0131474 filed in the Korean Intellectual Property Office on Dec. 21, 2010, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002](a) Field of the Invention[0003]Embodiments of the present invention relate generally to liquid crystal displays. More particularly, embodiments of the present invention relate to liquid crystal displays that can prevent partial stains due to a difference in cell gap, and methods of manufacturing the same.[0004](b) Description of the Related Art[0005]Liquid crystal displays, which are among the most popular types of flat panel displays, are typically composed of two display panels with field generating electrodes, such as a pixel electrode and a common electrode, and a liquid crystal layer between the display panels. These displays produce images by generating an electric fie...
